CHARLES HILTON KENNEY, OF NEW LONDON, CONNECTICUT.

MUFFLER OR SILENCER FOR GAS-ENGINES.

To all whom it may concern:

Be it known that I, CHARLEsH. KENNEY,

acitizen of the United States, residing at New London, in the county of New London and State of Connecticut, have invented a new and useful Mufiler or Silencer for I Gas-Engines; and I do hereby declare the following to be a full, clear, and exact de scription of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to the art of gas engines, and particularly to a new and useful mutiler or silencer for the same.

An object of the invention is the provision of a hollow spherical member provided with an irregular assage and provided'wit h an inlet, wit a cylinder including bafile means and connected to the spherical member opposite the inlet, said cylinder terminating in an outlet, which is in ali'nement with the aforesaid inlet.

Another object of the invention is the provision of a' pair of hollow spherical members, one having an inlet while the other is .provided with an outlet, and connected by a cylinder and battle means therein between the hollow spherical members.

In practical fields it may be found necessary to subject the minor details of construction to alterations, to which the patentee is entitled, provided the alterations fall within the scope of what is claimed.

The invention comprises further features and combination ofparts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings :Figure 1 is a longitudinal sectional view through the muflier, showing the irregular passages in the hol- Fig. 1. Fig 5 is a longitudinal sectional low spherical members. Fig. 2 is a sec tional view on line 2-2 of Fig. 1. Fig. 3 is a sectional view on line 3-3 of Fig. 1. Fig. 4 is a sectional view on line 4- 1 of view through another form of muflier showing different passages in the spherical members, and a slightly different form of baffle plate. Fi 6 is a sectional view on line 6 .6 of Fig. 5. Fig. 7 is a sectional view on line 7-7 of Fig. 5. Fig. 8 is a longitudinal sectional view through another form of muffier, in which only one spherical member is utilized. Fig. 9 is a'sectional view on line 99 of Fig. 8. .Figs. 10 and 11 are Specification of Letters Patent.

- plates 9 and 10, which are in alinement.

These plates are provided with openings 11 and 12. Projecting downwardly from the plate 10 is an arched or semi-circular curved plate 13 forming a passage 14, while upon the upper face of the plateis an-arched or semi-circular curved plate 15, which forms a passage 16. The passages 14 and 16 are offset from one another, in other words, they are diagonally disposed. Arranged in the cylinder 7 between the spherical members are battle plates 17 and 18. The upper portion of the battle plate 18 is provided with an opening 19, while the lower portion of the battle plate 17 is constructed with an opening; 20.

In using this form of improved muffler,

the same is screwed on to the discharge pipe for the products of combustion from a gas engine. The products of combustion pass into the chamber 21 of the spherical member 1 down through the openings 11 into the chamber 22, then through the passage .14, and thence through the openings 19 and 20 of the baffle plates 17 and 18, thus following an undulated course or loop, and subsequently through the passage 16, the chamber 23, the openings 12, and the chamber 24 to the spherical member 2, thereby leaving the outlet 4. i

In Fig. 5 the passages 14 and 16 are formed in tubular members 26 and 27, the I openings 11 and 12 being eliminated, while only one bafileplate 28 is utilized, which is secured to the spherical member 2, by the bolts 29.

In Fig. 5 the products of combustion enter the inlet 3' and circulate around the spheri cal member 1' through the port 30 into thetubular passage 14, into the chamber 31 and thence about the opposite edges of the battle plate 28, thereby subsequently passing through the tubular passage l6 through the opening 32 into the chamber 33, and

1 to 4 inclusive, and in lieu of the battle plates 17 and 18 a plurality of baflle plates 34 are provided, which are mounted upon a rod 35 journaled in bearings 36 and 37, there being sleeves 38 upon the rod between said bafile plates, for holding the same spaced apart. It will be observed that the bafile plates 34 do not engage the inner circumference of the cylinder 39 in Fig. 8, but in fact aspace 40 is provided. Adjacent the outer portion of every other bafile plate, a series of annularly arranged openings 41 are provided, while the intermediate baflie plates are provided with the plurality of openings 42 arranged annularly, and adjacent the sleeves 38. Upon reference to Fig. 8 the course of the products of combustion will be noted, owin to the arrows.

From the foregoing it will be noted that there has been devised a novel and efficient mutHer or silencer for gas engines, 'and one which has been found desirable and practical, owing to the novel but irregular passage, which through experiments has been found to mufiie the noise to a considerable extent.

In Figs. 1 and 5 the cylinders are provided with drain outlets 43 and 44 having the usual form of plugs. Also in Figs. 1,

.5 and 8 pipes 45 enter the spherical memsage forming a sinuous passage or course for products of combustion, and an inlet to said sinuous passage.

2. A mufller comprising a hollow spherical member provided with a centrally disposed division plate, an arched plate on said division plate forming an arched passage, chambers, one upon each side of the division plate, openings In said division-plate forming communications between said chambers, said chambers together with .the arched passage forming a sinuous passage or course for products of combustion, and an inlet to said sinuous passage, a cylinder secured to the spherical member and provided with baflie means forming an undulated passage into which the products of combustion from the sinuous passage enters. I

3. A muflier comprising a casing having sinuous assages at its ends, and provided with ba e means between said passages forming an undulated passage, the adjacent ends of said sinuous passages beingoflfset from one another.

4. A mufiler comprising a casing having spherical members at each .end provided with sinuous passages, one having'aninlet to the mufller, while the other has an outlet for the muffler, .the opposite adjacent ends of said sinuous passages being ofl'set from one another, said casing including a cylin der connecting said spherical members, batlie means in said cylinder forming an undu'lated passage of communication between sai'd sinuous passages.

5. mufller comprising a casing having sinuous passages at its ends, and provided with ba'flie means between said passages, and a fluid ejecting nozzle for ejecting the fluid into one of the sinuous passages.

6. A muffler comprising a casing provided. I with a fluid ejecting member and having a sinuous passage at one end, and provided with bafiied means adjacent said passage.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
